COMBINATION-LOCK.

Specification of Letters Patent.

Application led May 27, 1911.

Patented Sept. 5, 1911. serial No. 629,944.

To aZZ whom it may concern:

Be it known that I, MATTEO TAMBURINI, a subject of the King of Italy,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Combination- Locks,of which the following is a specification.

This invention relates to combination locks and it consists in certainimprovements in a combination lock constituting the subject of LettersPatent of the United States, No. 981,140, granted to me January 10th,1911.

One object of the invention is to construct the patented combinationmechanism so that it may be. used in a practical way to operate not onlya bolt but a latch, as well.

A further object of the invention is so to construct the parts of themechanism which directly include the index disks or dials that the samemay be concealed except when in use.

A still further object is so to construct the parts of the'mechanism soas to render it more compact and durable, and facilitate its operationby those familiar wit-h the combination.

In the accompanying drawing, Figure 1 shows the improved mechanism infront elevation as mounted in a door; Fig.2 shows the lock proper and apart of the operating spindle in perspective, the front plate of thelock being removed; Fig. 3 is a vertical sectional view in thelongitudinal plane of `the axis of the spindle and through that part ofthe mechanism which includes the index disks or dials; and, Fig. L is asectional view on the line m-m of Fig. 3.

In the door a is arranged a lock-casing Z; of usual construction, thecover not appearing in the drawings. Suit-ably guided to slide in thelock-casing are a bolt c and a latch al, c being a spring holding thebolt at any position to which it is moved and f a spring normallyholding the latch at its outward limit of movement. The bolt has aplurality of notches g in its under side, while t-he latch has a notch71, in one face thereof.

z' is an auxiliary bolt sliding in the lockcasing b and adapted to becont-rolled by a removable key The door a has the escutcheons Z0 and Zbearing against opposite faces thereof, the escutcheon 7c having anoutwardly projecting boss m. Fitting this boss is a cylindrical shell fawhich has an exterior annular shoulder 0 at its outer end and at itsinner end is formed with the threaded projecting stems p which penetratethe escutcheon 7c, the door a, the lock-casing b, and the escutcheon Zand carry at their free ends the nuts g which, when screwed up tight,clamp the shell and the escutcheons securely to the door. In the outerend of the shell n is fixed a head r.

The door a, lock-casing b and shell n, with its head r, affordsupporting means for the bolts, latch and springs already named,together with other moving parts, now to be described.

Journaled in the escutcheon Z and the head w is a spindle s carrying atits opposite ends the knobs t fixed thereto, the space between the lefthand knob in Fig. 1 and the escutcheon Z representing the distance whichthis spindle is longitudinally movable.

The spindle is provided with the wards u and fu, said wards beingrespectively adapted to engage the notched portions of the bolt andlatch c and CZ to move the same. The parts to be actuated (2'. c., thebolt and latch) being in the same vertical plane, but the two wards uand 'u being in different planes crossing the axis of the spindle, itfollows that when one of the wards, say u, is operatively engaged withthe bolt or latch member, say c, the other ward may rotate withoutengaging and operating the other member, and vice versa.

Arranged side by side in the shell a between the boss m and head r arethe rotary index disks or dials w the same and the head 1" havingindices on their outer peripheries, being penetrated by the spindle sand each having two internal circumferential grooves g/ connected by alongitudinal groove a. As in my patent referred to, coacting with thesegrooves in the dials are studs 2 on the spindle. When the spindle is inits right-hand position in Fig. 1 its ward u is in position to operatethe bolt c; when it is in the left-hand position its ward v is inposition to operate the latch cZ. In the latter position the spindle isin such position that, so far as the ward u and bolt c are concerned, itmay be moved longitudinally; it then remains only to move the dials 'wso that their indices will form the necessary combination with the indexon the head r to bring 'their grooves z in alinement With the studs 2.

It Will be observed that the shell n is provided with two sight-openings4. Each of these exposes one, two or more indices on each of the parts rand w. Normally to conceal the indices the shell a carries a sleeve 5having apertures 6 corresponding to the openings 4 in the shell. Whenthe sleeve 5 is in the position shown in Fig. 4 the indices are exposed.The sleeve 5 is embraced between the escutcheon 7c and shoulder 0.

In order 'that the escutcheon la may be removed from the shell andspindle after removing the combination .mechanism from the door the-escutcheon 7c is .provided With the vertical -slot 7 through Which theWards a and o of the spindle may pass.

Y Usually, spindle s Willstand at the left -in Fig. l (right-hand knob tengaging head r) and be held normally by the springactuated latch sothat Ward v projects downwardly; the disks fw may at that time preventmovement of the spindle to the right by being turned so that theirgrooves .e do not register With the studs 2. The spindle is in thisposition used to operate the latch.

Upon settingv the disks so as to allow-movement of the spindle to theright it may be brought to such a position :that Ward lv clears thelatch and Ward fa engages the bolt, whereupon the latter vmay be shot byturningV the spindle. Upon now returning the spindle to its original orleft-hand position in Fig. l and again disturbing the combination thebolt will be eHectually cut 0E from the influence of the spindle.

In order to hold the disks 'wagainst accidental displacementafteradjustment, as by rotation of the spindle, I provide a curved detent 8(Fig. 4) Which is pivoted in the opening 4 of the shell and may restflat against the peripheries ofthe disks, its toe 9 engaging notches l0in the disks and the detent being `held in that position by turning thesleeve to cover it; by turning the sleeve to uncover the detent thelatter may swingvout on its pivot (dotted lines, Fig. 4) to release thedisks.

Having .thus .fully described my invention, what Iclaim as nevvpanddesire to secure by Letters Patent is:-

l. The combination, Witha suitable supporting means, ofva rotarycontrolling member journaled and having limited .movement thereinlongitudinally of its yaxis and also having radial Wards, a latch `and abolt each movable longitudinally in said supporting means and crossingsaid member, one Ward being engageable With the bolt When said member isin one of its limits of longitudinal movement and the other Ward beingengageable With the latch When said member is at its other limit oflongitudinal movement and means, comprising an in- Looaes dexed rotarypart journaled in the supporting means concentric With said member, forholding the latter at either of its limits of longitudinal movement,substantially as described.
